Context
…you want to build a tool that helps people plan and navigate along routes - NAVIGATION SYSTEM. This system will be especially used by people like pedestrians, bikers etc. who travel at slow speeds.
Problem statement
Navigation systems for slow travelers require different functionalities than for example in-car navigation systems. How can these different requirements be accomplished?
Problem description with forces
Navigation systems for slow traveling people serve to a wide range of applications.
Some of them are needed indoor, for example as fair guides or to help departing passengers finding their way on an airport. Others will be used outdoor as city guides or even off-road on a walking-tour or when biking.
What these systems have in common is the main restriction their users have: they all travel at a low speed.
Due to this slow locomotion speed, every misguiding is very time consuming and exhausting to the pedestrian. For that reason it is of particular importance to determine the position of the user and calculate a route as exactly as possible.
In the same way a high detail level of the used maps is very important. To avoid far, exhausting and time consuming searches of single houses on a long street for example, every house number should be identifiable.
Since pedestrians have more time to observe a navigation systems' display without getting in danger by disregarding traffic, slow-traveler-navigation systems can provide much more information than in-car systems can (of course this information should not clutter up the display).
Additional location based services (LBS) can also be provided and be useful for users, for example displaying augmented building information in city guides or the position of the next available printer in an office.
Examples
As mentioned above, navigation systems for slow travelers are used on a wide range of application domains.
SAiMotion [1], for example, is a nomadic, situation aware information system that supports mobile user in complex environments such as a fair or an airport by giving them personalized location based information and navigating them through the environment.
NAVMAN GPS 3300 Terrain [2] is an off-road handheld navigation solution that helps users plan routes and guides them across any terrain.
The Lancaster GUIDE Project [3] aimed to investigate the provision of context-sensitive mobile multimedia computing support for city visitors. In the project a handheld computer-based context-aware tourist guide for visitors of Lancaster was developed.
Solution
Therefore:
Build a slow-traveler-navigation system that meets all the different requirements that are special to traveling at slow speeds.
Make positioning and route calculation as accurate as possible to avoid misleading the user.
Provide very detailed maps that show information like house numbers or for indoor navigation even special room information down to devices locations, etc.
